Having laid out this rule, Gorsuch then explains why discrimination against LGBTQ employees constitutes “sex discrimination” by laying out two examples.

Consider, for example, an employer with two employees, both of whom are attracted to men. The two individuals are, to the employer’s mind, materially identical in all respects, except that one is a man and the other a woman. If the employer fires the male employee for no reason other than the fact he is attracted to men, the employer discriminates against him for traits or actions it tolerates in his female colleague.

That is, if an employer permits its female employees to have sexual and romantic attractions to men but denies that same right to male employees, it is engaged in sex discrimination. It treats men differently than women.

Gorsuch also applies similar logic to a transgender employee:

Or take an employer who fires a transgender person who was identified as a male at birth but who now identifies as a female. If the employer retains an otherwise identical employee who was identified as female at birth, the employer intentionally penalizes a person identified as male at birth for traits or actions that it tolerates in an employee identified as female at birth. Again, the individual employee’s sex plays an unmistakable and impermissible role in the discharge decision.

This entire case falls apart if you get rid of the SEX protection lol. I love this because it should make everyone happy (but it probably won't). LGBTQ people get their protections and we still get to respect biology. Male/female are determined at birth.

One thing this doesn't do (like Tim Pool suggested) is that you can't claim to be a different species because this is about SEX. Tim Pool suggested you could identify as a tiger or something but that really doesn't apply.

Let's say Person X and Person Y identify as a tiger. If person X is a female and Person Y is a male and you fire them both then it's not sex discrimination.

The only way that would be sex discrimination is if you allow a male to be a tiger and not a female (or vice versa).
